The site is down for the third time in a month, after running without a hiccup since May. We haven’t changed anything. Whatever is going on is causing problems for other sites – including some used to administer our host’s business – on our shared server, so our host has taken us down. The folks at our host, uplinkearth, tell us the problem is with us. So, we’ll debug. In the meantime, we apolgize for the inconvenience.
